What distinguishes true Andaras from obsidian imitations is that there is always Etherium (prima Matra) present in genuine Andara Crystals. Etherium is a very rare combination of over 70 minerals that has a profound effect on our body and our subtle energy fields. The only available source of Etherium in the world is found on Lady Nellie’s land where the Andaras are present. True Andaras work with your DNA, greatly accelerating your perceptions by calibrating you mostly while you sleep, (Giving you lots of dreams).They work in your Heart and they work wonderfully with your intentions.
